Sponge Knob

Sponge Bob's knob.

Patrick sucked on his friend's Sponge Knob

Sponge Knob Bare Spanks

The act of ejaculating into an everyday washing up sponge, place aside and wait for the acquired time to harden. The female then strips the male of their lower attire and proceeds to spank them with the now hardened mallet.

'Do anything good last night?'
'Met that bird for a drink...insisted on watching a bit of Sponge Knob Bare Spanks'
'Ah man, what a slag!'
